CAN OPENER Filed July 8, 1927 IN UEN TOR Patented May 20, 1930 UNITED STATES REYBURN '1'. CHASE, OF CAMDEN, NEW JERSEY CAN OPENER Application filed July 8, 1927. Serial No. 204,878.

My invention relates to that type of can opener in which the top of the can is out out by a sheer blade set-at an oblique angle to the' top, and which is held down and pulled along by a toothed wheel rolling against the rim of the can.

The object of my invention is to provide a can opener that will be easy to make, easy to use, and that will cut the entire top out of the can so that contents of a solid nature will empty out in bulk; and that will leave the rim on the can so that contents of a liquid nature will not spillwhile the can isbeing opened; and that will leave no jagged or sharp edges to cut the hands. The rim being left on the can with the top out out smoothly and close to the rim leaves the can so that it may be used for other purposes after-the contents are removed. This opener can be made with as few as three pieces. Turning the key in one direction will start and continue the cut, and turning it in the other direction will open it for removal from the can. If desired, the blade may be made adjustable, or may be fastened to the frame by screws or clips so that it may be replaced by longer or shorter blades to cut cans with deeper or shallower to s.

attain these objects by the means illustrated in the accompanying drawings, in which- Fig. 1 is front view of the opener, mounted on a can in the cutting position, with a part of the can broken away to allow the shearing blade to be seen.

Fig. 2 is a view of the key side of the opener.

Fig. 3 is a view of the shearing side of the opener.

In all the figures, the numeral: 1 represents the frame, one portion of which is formed into the shearing blade 2, and other portions are formed into the guides 4 and 5 which hold the opener in its proper position on the can, and another ortion 6 is bent to form a finger, against whic 'the cam 7 which is attached to the key 8, bears and forces the shaft 10 up through the slot 3 when the key 8 is turned in a right hand or clock-. wise direction. This movement forces the toothed wheel 9 which is attached'to the'shaft 10, up against the lower ed e of the rim of the can, and forces the pointed corner 11 of shear blade 2 down against the top of the can, and a further movement of the key and attached parts causes the mm to pierce the top, and then draw the lade down to the shearing position,'when the shaft reaches the upper end of the slot and the opener is drawn along therimthus shearing the top close tothe rim. To remove the opener from the can, the key is turned in the opposite direction to that in which the cutting was done, and this causes the shaft 10 to recede down through the slot 3, thus releasing the opener so that it may be lifted oifthe can. I claim: v y

1. In a canopener, the combination of a frame; a traction wheel so mounted that-it may move across the body of the frame to engage or disengage therim of the can; means for turning the tract-ion wheel; a shearing blade mounted on the frame as a part thereof, and having a penetrating portionand a diagonal shearing edge, and means for forcing the traction wheel toward the shearing blade.

2. In a can opener, the combination of a frame having a pointed shear blade attached thereto and as a part thereof, and so made as to be rigidagainst the strains of cutting but resilient to allow the opener to pass over any enlargement of the wall of the can; a traction wheel arranged to engage the lower edge of the head of a can; means for turning the trac vtion wheel; means for allowi'n'g'the traction wheel to approach or re'cede from the shear hlade along the body of the frame and means for forcing the traction wheel toward the shear blade. i

3. In a canopener, the combination of a. frame having a shear blade attached thereto and as a part thereof; means for moving the frame normal to the'part to be cut for the purpose of puncturin it; and means for moving the frame along t e rim of the'can for the purpose of shearing the'adjacent part from the rim.

4. In a can opener, the combination of a frame having a shearblade as a part thereof; a traction wheel arranged to engage the under side of the rim of a can, and so mounted on the frame that it can move toward or away traction wheel; means for forcing the traction wheel toward the shear blade so that on the first movement of the traction wheel the blade will be forced through the metal of the Q 5 can; and a stop to limit the linear movement of the wheel so that as the rotation of the wheel continues a shear out is made.

v 5. In a can 0 nor of the type described, the

' combination 0 a slotted frame plate having 6 a laterally projecting arm adapted to ride on the bead of a can and a cutter blade rigid with, and disposed opposite the inner side of said frame plate, an operating handle having a shank extendin through the slot of said 15 frame plate, a eed wheel fast on the inner end of-said handle shank, and coo rating means on said frame plate and hand e operative to advancesaid feed wheel into gripping engagement with said bead when said handle 20 is turned in one direction.

6) In a can opener of the type described, the combination of a frame plate formed with an inclined slot, an integral laterally rojecting arm on one edge thereof adapte to 5 ride on the bead of a can, and an integral inwardlty extending cutter blade on another edge ereof lying opposite and substantially parallel with the. inner side of said frame late and formed with .a lower cuttinlg1 edge ao aving a iercing point, an operatin andle having a ank extending through tli slot of said frame plate a toothed feed wheel fast on the inner end of said handleshank, a lug onsaid frame plate, and a cam fast with said '35 hanidlfe heel with said lug to advance sai w mto 'ppi'ng .ehgagement with said beadwhen sal d handle is turned in on'edire'c'tiom V 1 7 7 TtjCHASEJ
